How much energy is released during the complete combustion of 470 grams of cyclobutane
At 25C, H2O2 decomposes according to the following equation. 2H2O2(aq) => 2H2O (l) + O2(g) .55V
One liter of a buffer solution is prepared by dissolving 0.115 mol of NaNO2 and 0.070 mol of HCl in water. What is the pH of this solution? If the solution is diluted two fold with water, what is the pH?
construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
In an experiment for measuring water hardness in a water sample, using Atomic Absorption Spectrophotometry, I obtained a value of 173.74 ppm hardness for my water sample.
